Environmental performance of biogas produced from industrial residues including competition with animal feed - life-cycle calculations according to different methodologies and standards
Today incentives for an increased use of biofuels exist, one being the EU Renewable Energy Directive (RED). In this article the environmental performance of biogas systems using industrial residues from biofuel and food industries as substrates are analysed using a life-cycle perspective. These substrates are interesting since they do not compete directly with agricultural land for food production
